Recommended Sequence For Adjusting Gear Set

Recommended sequence for adjusting gear set
If shaft bevel gear and head bevel gear have to be adjusted, the following sequence is recommended for maximum efficiency:

1. Adjust friction torque and shaft bevel gear (S 3)
- Set pre-load of tapered roller bearing for shaft bevel gear via friction torque measurement.
- Determine thickness of adjustment shim S 3 "and" insert. This secures shaft bevel gear axially, that the dimension from center of head bevel gear to the face of shaft bevel gear corresponds to the installation dimension "R" determined during production.
- Perform check measurement for S 3.

2. Adjust head bevel gear (S 1 and S 2)
- Set pre-load of tapered roller bearing for head bevel gear via S total.
- Adjust backlash. Select thickness of adjustment shims S 1 "and" S 2 so that the specified backlash is present between shaft bevel gear and head bevel gear.
- Checking backlash

The object of the adjustment is to reproduce the setting for quietest possible running, as obtained on the test machine in production. Maximum care and cleanliness are essential for achieving good results when performing repairs and taking measurements.
